This invention relates to an attachment for sewing machines, the general object of the invention being to provide means for folding over the edges of two pieces of material and guiding an edge of a third piece between the folded over edges so that the needle of a single needle sewing machine can sew the pieces together, the invention being mainly designed for joining the front and rear portions of a shirt to the of the shirt. V

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described. illustrated yokes at the shoulders in the accompanying drawing and speciflcal-' ly pointed out in the appended claim.

In describing the invention in detail, reference wil be had to the accompanying drawing wherein like characters denote like or corresponding parts throughoutthe several views, and in which Figure 1 is a top plan view of the attachment. v

Figure 2 is a view looking toward the outer edge thereof. 7

Figure 3 is an end view showing in dotted lines the material passing through the device.

Figure 4 is a detail view showing how the three pieces of material are positioned by the device.

Figure 5 is a detail view showing how the material is arranged when engaged by the,

needle. r V In this drawing, the numeral 1 indicates a plate which is provided with a pair of oblong openings 2 adjacent one corner there- 7 of so that the plate can be fastened by set screws or the like to a part of a singe needle sewing machine. Intermediate the ends of the plate is an upwardly curved portion 3 having a top part which slopes downwardly from the far edge of the plate to the inner edge or that edge which is nearest the needle. A vertical part 4 is connected to the edge of the horizontal part and has a substantially horizontal flange 5 extending inwardly from its lower edge, the flange gradually increasing in width from the outer end of the part 4 to its inner end and this flange is spaced from.

'end of the flange 5 and extension of the end of folded portion of the plate 6, for guiding the the horizontal part of the portion 3] A plate 6 has its inner end bent into a loop with its extremity connected with the top part of the portion 4. A substantially 'U shaped part i 7 has one edge connected with the part 4 and this part 7 loopsaround the loop'part of the portion 6. Thus the portion 3 and the flange 5 forms a'space rial A when said piece A passes over the right hand part of the plate 1 and the space between the loop part of the member 6 and the part 7 will form a loop a in a piece of material A as the same passes over the part 6. The piece of materia B has one edge guided in the space formed bythe horizontal part the hor'zontal part of which will form a loop a in a piece of mate- V of the portion 3 and the lower part of the portion 7 and as all vof these wardly toward the needle the looped edges of the pieces A and A and an'edge of the piece B are brought together, as shown in igure 5, so that'the needle of the machine can sew the edges together.

As before stated, the machine is mainly designed for sewing the front and rear portions of a shirt to the shoulder yokes thereof. Tongues 8 are placed on the needle side of the devce, one formingan extension of, the the other forming an the lowerpart of the spaces slope downmaterial tothe n'eede. v I p It is thought from the foregoing descrip tion that the ad'va'ntagesandnovel features of the invention will be readily apparent.

It is to be understood that changes may be side of the device.

made in the construction and in the combination and arrangement of the severalparts,

provided that such changesfall within the scope of the appended claim. I

" What we claimis:- p

A folder of the character described comprising a plate formed with anupwardly and laterally curved portion inclined transversely of said plate, a vert cal portion rising from the outer edge of said first named portion and having a flange extending inwardly spaced below the upwardly and laterally curved por-' tion. the flange being gradually increasedin width from end to end, a plate having a loop joine upwar named portion, second named portion an of the plate and sp from, said flange, loops and plate being inclined correspondingly to the incline. of the dly and laterally curved portion.

' In t stimon'y'whereof we afiix our signatures."
